Kamilov I. K. , Aliev Kh. K. , Omarov A. M. , Omarova N. N.
The differential susceptibility of yttrium orthoferrite was measured for magnetic fields in the range 0-35 Oe and for temperatures in the range 283-670 K. The compound YFe03 has a Lifshitz critical point, which arises due to rearrangement of the domain structure.
